Title: Transmission control method
Inventor: SAKUMA NOBUHARU
IPC: H04L12/42
Filed: 1990-03-29
Abstract: PURPOSE:To avoid deterioration in the transmission efficiency and response delay by registering a function code before relay and a function code after relay in pairs for function codes set to each repeater and setting a function code to be relayed to only a required repeater. CONSTITUTION:A function code representing a content of a message is added to each message, and a function code before relay and a function code after relay corresponding to the function code before relay are registered to each of repeaters 1020, 1330 and 2133. When a message is inputted from a loop transmission line 1 connecting to, e.g. the repeater 1020, a function code after relay corresponding to a function code before relay is added to the inputted message when a function code coincident with the function code of the inputted message in the function code before relay registered in the repeater 1020, the function code after relay corresponding to the code is added to the inputted message and the result is sent to other loop transmission line 2. Thus, the message is sent through only a loop requiring the message and the delay in response is avoided.

Title: Flour for batter and production thereof
Inventor: OKUMURA MINORU
IPC: A23L7/157
Filed: 1985-04-13
Abstract: PURPOSE:To produce flour for batter capable of giving fries having a constant application rate of coating, by heat-treating rye raw hull and grinding the hull into fine powder. CONSTITUTION:Rye in the form of raw hull is heat-treated and then ground into fine powder to produce flour for batter. The heat treatment is carried out under conditions satisfying the following relational expressions; 90<=T<=120 and TM<1/2>=350+ or -100 formed from the material temperature (T deg.C) and the holding time [M (min)]. The above-mentioned relational expressions are based on experimental data. If the material temperature is lower than the lower limit 90 deg.C, particularly <=85 deg.C, the temperature is insufficient for pregelatination. If much time is taken, effect cannot be expected. The product is somewhat raw and assumes a foamlike form with enormous cells. If the temperature exceeds the upper limit 120 deg.C, the product is unfavorably colored or causes scorch smell. In the relation between the material temperature and the holding time, a value exceeding the upper limit produces less bad influence than a value below the lower limit.
